![每天一博–第三天 安装docker及通过docker部署nginx [ dockerfile方式 ]-陌上烟雨遥](https://wallpaper.moluyao.wang/wp-content/uploads/2024/06/QQ截图20240604170558.png)
不同的操作系统，使用的安装工具不同，我用的是manjaro，arch的衍生版本，使用的是pacman，Ubuntu的是apt-get，Centos/Redhat的是yum，但是安装方式不尽相同。
<span class="token function">sudo</span> pacman -Syy docker <span class="token function">sudo</span> systemctl <span class="token function">enable</span> docker <span class="token function">sudo</span> systemctl start docker<span class="token function">sudo</span> pacman -Syy docker <span class="token function">sudo</span> systemctl <span class="token function">enable</span> docker <span class="token function">sudo</span> systemctl start dockersudo pacman -Syy docker sudo systemctl enable docker sudo systemctl start docker
如果是测试环境中，安装docker前可以将selinux，firewalld关闭，正式环境中需要将docker服务在firewalld的zone–service中开启，并开启相应的端口。
Docker-Compose项目是Docker官方的开源项目，负责实现对Docker容器集群的快速编排。
本文主要讲解如何通过dockerfile创建docker container，将不通过docker-compose进行创建管理
